Surface Transportation Efficiency Analysis Model (STEAM)
|FHWA > STEAM > Related Links > IMPACTS Spreadsheet|
IMPACTS is a series of spreadsheets developed to help screening-level evaluation of multi-modal corridor alternatives, including highway expansion, bus system expansion, light rail transit investment, HOV lanes, conversion of an existing highway facility to a toll facility, employer-based travel demand management, and bicycle lanes. Inputs are travel demand estimates by mode for each alternative. The impacts estimated include costs of implementation, induced travel demand, benefits including trip time and out-of-pocket cost changes such as fares, parking fees and tolls, other highway user costs such as accident costs, revenue transfers due to tolls, fares or parking fees, changes in fuel consumption and changes in emissions.
